Im in brisbane, and i thought about b16/18 swap but i estimated around 4k, (is this correct)
i thought that if it was just seals it would be alot cheaper.
I didnt think it was that wrecked because the engine still runs great, doesnt seem sluggish or anything.

Do you think its needed to remove the head? coud it be that the seals are the majority of the problem? or would that be rare?
